THE long-range UK summer weather forecast has been released and it reveals Britain is set for a scorcher with THREE MONTHS of roasting sunshine on the way.

A massive plume of scorching air from Africa poised to engulf the UK bringing near 90F heat until August, according to some forecasts.

After weeks of dreary weather Britain is already warming up with thermometers set to hover around the 25C (77F) mark at times this week.

Another burst of extreme heat is forecast in two weeks around the beginning of June – the start of the meteorological summer.

Some long-range experts are now promising weeks of unbroken sunshine and record breaking temperatures over the coming months.

However extreme heat surging across Britain from Africa and the Continent will trigger violent spells of thunder and torrential rainfall, they warn.

James Madden, forecaster for Exacta Weather, said the next three months will bring a succession of “major” heat blasts.

He said despite some cooler periods throughout the season as a whole, the overall theme this year is hot and sunny.

He said: “Heat surges and Spanish pluming from the near Continent will be part and parcel of the upcoming summer 2017 period.

“It will not be entirely settled throughout and there will be an increased risk for some mixed and cooler weather at times.

“Atmospheric conditions will be favourable for vigorous and widespread thunderstorm activity, hefty hail showers and the risk for some newsworthy flood events.

“However, despite these unsettled periods, it is of the highest confidence that multiple and major heat surges will occur throughout this summer.

“Early projections consistently indicate that this summer could break or near a number of temperature records in terms of maximum heat, and we are only weeks away from temperatures approaching or exceeding the 30C mark for the first time this year.”

Piers Corbyn, forecaster for WeatherAction, said: “There will be some very warm periods over the summer thanks to warm air coming up from Africa.

“There will some also be cooler periods and this is mainly due to the jet stream once again showing some wild deviations over the next three months.

“The largely dry conditions are expected to continue and this is likely to mean there could be water shortages.”

The Met Office’s long-range contingency planner said temperatures are likely to remain above-average until the end of July with dominant high pressure promising frequent sunny spells.

It states: “The Met Office Long-Range Prediction System, along with systems from other forecast centres, shows an increase in the chances of an anticyclonic influence across the UK in May.

“This circulation pattern gives an enhanced likelihood of more frequent sunny spells and winds from a continental flow.”

The outlook explains that higher than normal North Sea temperatures around the UK point towards the likelihood of above-average temperatures through the start of summer.
